RESUMO

Epilepsy is one of the most common neurological diseases with a prevalence ranging from 0.5% to 2% in different sittings. The World Health Organization (WHO) estimated that nearly 80% of this burden is borne by resource-poor countries where even conventional electroencephalogram (EEG) coverage is dramatically short.  Video EEG monitoring applied for days as conducted in epilepsy monitoring units (EMUs) is aimed at seizure localization, anti-seizure medication (ASM) adjustment, or epilepsy surgery evaluation and planning. However, the EEG approach in EMUs has its obstacles. The present article is aimed to concentrate on the logistic challenges of EMUs, discussing existing data and limitations and offering suggestions for future planning to enhance the utilization of existing technology. Shortages of adult and pediatric epileptologists, qualified nurses, as well as EEG technologists have been reported in different countries. Moreover, injuries and falls, psychosis, status epilepticus, and unexpected death have been stated to be the most frequent safety issues in EMUs. Enhancements to mitigate logistical and healthcare system-related barriers in EMUs include the implementation of large cohort studies and the utilization of artificial intelligence (AI) for the identification and categorization of specific risks among EMU admissions. The establishment of EMUs and their associated challenges and barriers are best acknowledged through discussions and dialogue with various stakeholders.

RESUMO

Cerebral venous sinus thrombosis (CVST) is a rare neurovascular condition that has been observed in individuals with coronavirus disease 2019 (COVID-19). This systematic review aimed to explore the sex differences and characteristics of concurrent COVID-19 and CVST cases. A total of 212 CVST patients were included in the study. Women with CVST had a slightly higher mean age compared to men (47.359 years vs 46.08 years). Women were more likely to report symptoms such as fever (56.1%) and decreased sense of smell or taste (71.4%), while men more frequently experienced nausea or vomiting (55.6%), headache (62.9%), and seizures (72%). Notably, current smokers, who were predominantly men, had a higher occurrence of CVST. On the other hand, women had a higher likelihood of CVST risk factors such as oral contraceptive pill (OCP) use and autoimmune diseases. Treatment approaches also showed sex-based differences. Unfractionated heparin was administered more often to women with CVST (63.2%). The in-hospital mortality rate for CVST patients was 21.3%, with men having a significantly higher mortality rate than women (65.2% vs 34.8%, P = .027). Survival analysis revealed that factors such as smoking history, diabetes mellitus, hypertension, OCP use, COVID-19 symptoms, CVST symptoms, and the need for intubation significantly influenced survival outcomes. Understanding these sex differences in COVID-19-related CVST is crucial for accurate diagnosis and effective management, ultimately leading to improved patient outcomes. Our findings highlight the importance of considering sex as a factor in the evaluation and treatment of individuals with COVID-19 and concurrent CVST.

RESUMO

Pressure ulcer (PU) is a localized injury to the skin or underlying tissues usually over a bony prominence, which results due to pressure or pressure in combination with shear. It is an expensive health care problem that have deterring impact on the length of hospitalization and cause extra nursing care time. Moreover, PUs negatively impacts patients' health related quality of life. High PUs prevalence figures were found in specialized hospital units such as intensive care unit (ICU), orthopedics, surgery, and also in stroke patients in medical units. The major purpose of this study is to assess the frequency of pressure ulcers in stroke patients at Ayub teaching hospital. The methodology used for carrying out the research was cross-sectional study conducted during months of September, October, and November 2020. Questionnaire was used to collect the data and well-informed written consent was taken from the patients. A total of 120 stroke patients were initially included with the intention to study the frequency of PUs among them. Different age groups were taken but majority (48.3%) belonged to the age group 31-60 years. Maximum patients were hypertensive (65%), while few of them were diabetic (35%). From the results of proposed work, it is found that out of 120 stroke patients, 75.8% presented with ischemic stroke while 24.2% presented with hemorrhagic stroke. 8.3% that is 10 out of 120 stroke patients developed pressure ulcers of grade 1 (1.7%), grade 2 (1.7%), grade 3 (2.5%), and grade 4 (2.5%) mostly in the sacral region (6.7%) and also on ankle (0.8%), and shoulder (0.8%) respectively. Patients in the study group had unsatisfactory hygiene (6.7%) were malnourished (11.7%) and were not using preventive mattresses (79.2%). Those at the risk of developing pressure ulcers were not being repositioned (6.7%) and did not had awareness (10%). Prevention and treatment used in ward is 100%. Conclusively, the frequency of pressure ulcers in stroke patients was determined to be 8.3% and the most frequent localization was sacrum. The PU care in this hospital is appropriate but still could be improved further by improving risk assessment, prevention specially use of air mattress and patient education regarding PUs. The main objective of the study is to identify the frequency of PUs in stroke patients and to highlight various factors that would avoid PUs development.

RESUMO

With the advancement in technology, machine learning can be applied to diagnose the mass/tumor in the brain using magnetic resonance imaging (MRI). This work proposes a novel developed transfer deep-learning model for the early diagnosis of brain tumors into their subclasses, such as pituitary, meningioma, and glioma. First, various layers of isolated convolutional-neural-network (CNN) models are built from scratch to check their performances for brain MRI images. Then, the 22-layer, binary-classification (tumor or no tumor) isolated-CNN model is re-utilized to re-adjust the neurons' weights for classifying brain MRI images into tumor subclasses using the transfer-learning concept. As a result, the developed transfer-learned model has a high accuracy of 95.75% for the MRI images of the same MRI machine. Furthermore, the developed transfer-learned model has also been tested using the brain MRI images of another machine to validate its adaptability, general capability, and reliability for real-time application in the future. The results showed that the proposed model has a high accuracy of 96.89% for an unseen brain MRI dataset. Thus, the proposed deep-learning framework can help doctors and radiologists diagnose brain tumors early.

RESUMO

INTRODUCTION: Acute transverse myelitis is an uncommon inflammatory, intramedullary, disorder of the spinal cord. Spastic paraplegia, impaired sphincter functions, and sensory loss, with sensory level, are the clinical manifestations of this devastating disorder. The utilization of magnetic resonant imaging (MRI) contributes to the surge in the diagnosis of more ATM cases. Although the causes of ATM are numerous, both Mycoplasma pneumoniae and Schistosoma mansoni are uncommon causes and their co-existence in the same patient has not been reported before in Saudi Arabia. CASE: We report a 25-year-old ATM male patient presented with a history of sudden onset severe low back pain. Within four hours from the onset of the back pain, he became completely paraplegic with impaired functions of the bowel and urinary bladder sphincter. Furthermore, he lost all modalities of sensory functions in the lower limbs. His examination revealed spastic complete paraplegia with sensory level at T6. Clinical neurological examination revealed normal upper limbs and brain functions. The MRI of the cervico-dorsal spine showed extensive longitudinal hyperintense lesion extending from the upper cervical segments to the lower dorsal segments (extensive longitudinal transverse myelitis). A post-infectious immune-mediated predisposition was highly suspected due to the very high titers of anti-Mycoplasma pneumoniae IgM and IgG that were detected. The immunosuppressant therapy did not improve his paraplegia. A spinal cord biopsy revealed the presence of several Schistosoma mansoni ova surrounded by chronic inflammatory reactions and reactive gliosis. CONCLUSIONS: Both Mycoplasma pneumoniae and Schistosoma mansoni should be investigated in cases with extensive longitudinal ATM.

RESUMO

BACKGROUND: This report highlights a rare case of simultaneous bilateral blindness due to posterior ischemic optic neuropathy. Typically, ophthalmic involvement in giant cell arteritis is monocular or sequential ischemia of the anterior portion of the optic nerve, and less frequently simultaneous. CASE PRESENTATION: An 80-year-old Saudi male came with a history of simultaneous bilateral vision loss 5 days prior to presentation. The exam showed dilated non-reactive pupils, no light perception in both eyes, and normal fundus exam. C-reactive protein and erythrocyte sedimentation rate levels were high Magnetic resonance imaging and magnetic resonance angiography of the brain showed a right posterior optic nerve lesion and absence of flow in both ophthalmic arteries respectively. A left temporal artery biopsy confirmed giant cell arteritis. CONCLUSION: The presentation of GCA can be atypical and patients may present with simultaneous blindness. Bilateral simultaneous PION does not exclusively occur in a post surgical setting, emphasizing the importance of decreasing the threshold of suspicion of similar cases to avoid further neurological complications.
